JOHN B. AUFULDISH, OF DAYTON, ASSIGNOR TO THE COLUMBIA CASH REGISTER COMPANY, OF MIAMISBURG, OHIO.

CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 516,856, dated March 20, 1894.

Application filed January 23, 1893.

To all whom it may concern:

Be it known that I, JOHN B. AUFULDISH, of Dayton,county of Montgomery, State of Ohio, have invented a new and useful Improvement in Cash Registers and Indicators, of which the following is a specification.

My invention relates to improvements in 7 cash registers and indicators.

The object of the invention isto simplify the construction of the same by reducing the number of operative parts, and yet produce a register meeting all the requirements of a cash registering and indicating medium, and further, to so arrange the registering mechanism that the registration of a sale is made by the return or upward trip of the key-lever last operated, while the amount is indicated on the tablet by the downward trip of the key-lever.

To these ends my invention consists in' various mechanical elementsthrough the agency of which sums of money may be registered and indicated.

The elements comprising the improvements will be fully described in the specification, and the several combinations thereof, set forth in the claims.

The drawings herewith presented as sup; plemental to the specification, illustrate the salient features thereof.

The same reference characters will be used to indicate corresponding parts in the different views, of which- Figure 1. is a vertical view, showing a rear plan of the registering mechanism, with the rear of the casing broken; Fig. 2. a vertical view, looking from the front, showing the transferring mechanism, that carries values from the wheel of a lower, to that of ahigher denomination; Fig. 3. a side elevation of the machine, partly in section with a side thereof removed; Fig. 4. a detached,detail view of the segmental grooved sliding plate; Fig. 5. an edge view of the same; Fig. 6. a cross section, horizontally through the center of Fig. 4, on line'0c-x; Fig. 7. a detached,detail side view of the main wheel registering arm; Fig. 8. a detached, detail plan view of the same; Fig. 9. a detail, detached end view of the same, showing the slot therein; Fig. 10. a detached, detail view of the sliding bar adapted $erial1lo.459,50l.

Parts are broken away, one of the tracks for the rollers is shown in section. Fig. 21. is an enlarged sectional view of one of the corners of the money receptacle, showing a part of the rolling cover, the side of the cabinet in section, and a roller, the track for the rollers also appears in section. Fig. 22 is a detached, detail view of the main registering wheel showing the cam ring thereon, the lower, portion of the wheel broken away.

A indicates the housing or inclosing case for the operative parts,into the sides of which the main shaft B is journaled. Upon this shaft a series of curved or graduated key-levers O are fulcrumed, having finger tips upon the outer ends, bearing numbers representing different sales to be recorded. Upon the main shaft, forwardly projecting arms D support the horizontal oscillating adding bar B, this adding bar is divided into sections, each section having its arms independent of the adjacent section, and designed to operate a main or primary wheel E upon which the cent or values of a lower denomination are registered. I have-shownin the drawings but a portion of one of the sections of this oscillating bar, and but one arm extending from the main shaft 13, it will be understood however, that two or more arms D are requisite to give the bar a suitable connection with the main shaft. A horizontal brace B", shown in section in Fig. 3, is used for the purpose of giving the parts a suitable and substantial bracing and thereby prevent any possible lateral or uneven movement under the action of the keys. The graduated or curved por tion of the key-levers 0, through which the adjustable set screw a extends, operates the bar, to depress it a distance corresponding to the value of the keylever, which valuation is measured according to the extent of the curve C or the distance from the point of the adjustable set screw and the straight part of the key-lever. A vertical pitman b r is pivoted to the bar B, at the rear of the main wheel E, the upper end of which is pivoted to the reciprocating registering arm 0 pivoted to the axis of the main wheel and extending radially to the circumference thereof. This arm is provided with a rectangular slot 0' horizontal to the axis of thearm,into which a similar shaped sliding piece 0 provided with a rounded surface tooth c and a pin 0 in close proximity to each other, though adapted to perform distinct and separate functions both of which will be hereinafter fully detailed. A second horizontal vibrating bar 13 is pivoted to the main shaft in a similar manner to that of B, by forwardly projecting arms, one of which is shown at D in Figs. 2 and 3. This bar, together with the bar B and the key-levers, is brought to a normal upward position by springs a, aZa attached to a horizontal bar (I, rigidly attached to the ends of the casing at a suitable distance from the vibrating mechanism. To the bar B is pivoted a vertical rod or pitman b, which is immediately and adjustably connected at its upper end to a vertical sliding plate 6 having slots through which are inserted screws 6 securing it slidingly against smooth surface bearings on the rear of the front part of the casing. A pendent cam c is pivoted to this vertically sliding plate, and is maintained in the position shown in Fig. l by a wire spring 6 bearing against the edge thereof. The shape of the inner surface of this cam has much to do with the successful operation of my invention, and will be dwelt upon at greater length as other conjoint or COOI erative parts are mentioned. At an intermediary point between the plate 6 and the toothed wheel E, a segmentalgrooved sliding platefis secured by means of slotted ears f and f, through which broad headed screws are inserted; guides or flanges f projecting from the casing furnish additional means to prevent an uneven movement of the same. From the center of this plate an extension f is provided upon which is placed a pin f adapted to occupy a position in one of the slots in the vertical plate 6 and adjacent to the cam 6 a post g also extends at right angles from the extension f to which is rigidly attached one end of a transverse, adjustable rod 71, the other end of said rod being secured likewise, to a sliding piece having teeth h, 71.2, which are adapted to slide in and out of engagement with the teeth on that side of the wheel.

It will be seen that the segmental grooved plate f, controls in its operation, all parts that are directly attached to it, to-wit, the transverse rod h with the plate having the teeth 71' and 7L2, and the bar 0 that fits in the slot in the arm 0, and therewith the tooth a, while the cam 0 controls, when actuated by the downward movement of the vertical plate c, the segmental grooved plate, by compelling the pin f to trip the inclined surface of the cam 6 thereby withdrawing the segmental grooved plate in the direction of the cam, and allowing it to return again to its former position after the trip of the pin has been made, and thereby release the segmental grooved plate, to engage with a tooth and effect a registration by its backward movement in the direction of the arrow, Fig. 1, the extreme limit of which is shown in the position of the arm 0, a position it is normally in, prior to the operation of akey. The operation of this mechanism to effect a primary registration is as follows: Looking at Fig. 3, it will be observed that the adding bar B, having an operating connection with the registering arm 0, is actuated by the curved or graduated part of the key-lever to travel a distance downwardly, corresponding to the value of the key, which valuation is measured on the toothed wheel E, by a certain number of teeth; different numbers of teeth indicating the diit'erent values of the keys; for instance, for the five cent key, the wheel would be moved to theextent of one tooth, while for the ninety five cent key, it would be rotated a distance of nineteen teeth, the registration being effected as the key-lever returns to its former position, and not as it is being depressed; the values however, may be regulated to suit the character of business. Referring now to bar B this bar as before stated, is located directlyin front of the add ing bar B and bears against the level part of the key-levers, therefore it is not aifected when depressed, by the different gradnations of the keys, but descends the same distance for each key, thisimpartsto the vertical sliding plate 6 a regulated, systematic movement, and therewith the pendent cam 6 In Fig. 1, it will be noted, the extreme lower point of the cam bears immediately on the pin f on the segmental grooved sliding plate f, and

against a side of the central slot in the plate e, upon the depression of the bar B by any one of the key-leve1's,tl1e cam is brought; downwardly, the pin makes the trip of the cam, as shown in dotted lines in Fig. l, and assumes its former position. As the camdescends,the segmental grooved platefis drawn horizontally "tooth in the Wheel E.

to the right, looking at Fig. 1, as the pin begins the travel of the right hand side of the cam, the grooved plate thus actuated, draws with it, the sliding bar 0 having the tooth 0 which action frees the tooth from the teeth of the wheel, while the registering arm a is being carried downwardly, and in the same instant the grooved plate f draws the transverse rod h, having the plate with teeth It and W, the said teeth thereby becoming engaged with the teeth at that side of the wheel, to hold it firmly, while the registering arm is descending to engage with a tooth, which it is permitted to do when the pin f trips the earn; the springs i-i serve to slide the segmental grooved plate back to its normal position, when the pin f has completed its trip of the cam.

To practically illustrate a registration, the key having the value say of thirty cents, is pressed, the pin f trips the cam 6 at the same moment the tooth c on the registering arm 0 arrives at 30 on the wheel E, and is permitted to engage therewith by the grooved plate sliding to the left, looking at Fig. 1; this action also backs the teeth h and 71 out of gear and the wheel is thereby permitted to be carried backward in the direction of the arrow to complete the registration, thus it will be seen that the wheel E is under absolute control at all times.

Suitable stops may be employed to prevent the slightest vibration incident to the mornentum imparted to the wheel from carrying the arm 0, a trifle too far, by providing small stops or projections on the ends of the casing against which the bar B stops, also an angle piece,j is attached to the casing, for the registering arm 0 to come against when said arm has reached the limit of its upward travel. A ring it, is secured to the front of wheel E indicating the value of each tooth, which successively appears through a sight opening the contour of the rim of this ring is irregular, to form-a cam surface as shown at 10 a transferring arm 10 having alaterally projecting stud k at one end, and a slot k at the other, is pivoted adjacent to said rim, in a way to project the stud. 70 at right angles to and parallel with the periphery of the rim, upon which, the arm has a normal tendency to rest.

The pin is, attached to the adjustable piece 70" secured between the ring and the wheel E, is carried around by the rotation of said wheel; and passes over the pin 15 thereby pressing that end of the arm into the cam surface 10 and causing the arm to vibrate in its pivot, which'in turn actuates the pawl Z to move one A stud Z" projecting from the lower end of this pawl penetrates the slot k and is drawn downwardly by the arm 70 This pawl is further, provided with a pin Z extending through it at right angles near the upper end, the inner end of which is inclosed in the downward curve of the connecting finger m, attached to the upper end of the segmental grooved sliding plate f, see

Fig. 1 this is the means by which the tooth of the pawl is withdrawn from the tooth of wheel E, at the same time the transfer arm 76 slides the pawl up one tooth. The outer end of the pin Z regulates the movement of the pawl, by being confined withinthe limits of a rectangular recess in the plate a, attached to the casing, and against which the pawl is pivoted. A checking pawl Z with spring Z maintains the wheel securely when the registering pawl Z is withdrawn by the action of the segment plate f, and thepawlis' freed from contact with the wheel.

I employan improved means to prevent the operation of more than one key at a time, detail, detached views of which are set forth in Figs. 16 and 17. A horizontal plate or grid J having alternate bars and spaces, is secured to the ends of the casing at a suitable distance to allow each key-lever to penetrate the space between the bars. The grid is located on a horizontal line at right angles to and between the fulcrum and the rear end of the key-levers, and the key-lever at that point requires specially designed features as shown at p, p for purposes to be hereinafter mentioned.

The bars p--p, are provided with a transverse slot in which a series of individual sliding cams p are adapted to slide, being provided with longitudinal slots, through which screws enter, to secure them slidingly in said slots, see Fig. 17.

Fig. 16 shows several keys in section, one of them occupying a position midway between the points of two cams, in which position it prevents the passageof anyotherkey. Theinclined portion 19 of a'key readily separates the points of these pieces by engaging with their inclined surfaces, which has the effect of closing up all the adjacent spaces so that another key cannot enter, and thus it will be seen, that should two keys be actuated at the one time, each will in effect press the cams toward the other, thereby preventing either from ascending the space between the bars of thegrid, until pressure is removed from one. When the keylever has traveled the full extent of the space the rounded offset 19 still separates the adjacent cams and readily returns by the pressure exerted by the spring a to its former place. Sheet 5 is confined to detached detail illustrations of thetablet-indicating mechanism included as an elemental part of my invention; though not shown relatively associated with other parts, its operation will be understood. Each key is provided with a separate and independent slotted lever q pivoted thereto at a suitable point and in a suitable way in the front of the fulcrum; one end of a bell crank q is pivoted to the slotted end of the lever, the other end of the bell crank supports the tablet g Suitable bearings are provided in the horizontal bar R rigidly secured to the ends of the casing in a central position, the horizontal bar B being secured to the upper surface of the bar R whereby suitable boxes for the crank shafts are formed. The ends of the bar Rare bifurcated so as to straddle the downwardly projecting parts r of the horizontal grid R which is provided with anti-friction rollers r at both ends by which the grid R is subjected to a vertical movement; a vertical track 7" shown in cross section Fig. 20 is located on the ends of the casing and furnishes a rolling surface and a guide for the rollers. 18, shows two tablets, in elevated and lowered position; a pin or detent r secured to the shaft of the bell crank maintains the tablets in their respective positions when elevated or lowered; in the former instance, the detent, in the rotation of the bell crank by the depression of a key-lever, is brought against the under surface of the grid R which is raised until the detent reaches the space therein, when the grid rolls downwardly to its former position with the detent inclosed vertically in the space, and the tablet raised, all of which is shown in Fig. 18. In the operation of elevating the tablet the lever connecting arm of the crank makes the travel shown in dotted lines; the lever travels a distance upwardly corresponding to the length of the slot therein before the arm of the crank is affected by its movement. A tablet thus elevated re mains exposed until the depression of another key operates its respective crank, the pin or detent on which is rotated against the surface of the grid thereby elevating the same, and releasing the pin or detent of the tablet exposed; the same instant that this detent is released, the one that releases it enters its respective space and exposes another tablet. Spiral springs 0' apply tension to the bell crank by which the detent r and the tablet are drawn to the horizontal position shown in full and dotted lines in Fig. 18. The tablet is prevented from falling to a lower plane by the detent coming in contact with the surface of the bar R, as appears in Fig. 20. The cash receptacle is provided in the base of the cabinet, and is stationary. The cover therefor consists of a plurality of panels 0, connected longitudinally by hinges 0', each panel has a roller 0 attached to its under-surface at each end, a track 8 is secured to the ends of the cabinet upon which the rollers travel, a detent s secured to thelower panel at both ends adapted to engage with a similar detent s is pivoted to the ends ofthe cabinet, and actuated to release detent s and thereby permit the panels to slide backwardly, underthe tension of a spring that may be secured to the rear panel and to the rearward part of the cabinet.
